I am looking for a similar deal (except the white 60GB ipod). The cheapest I have seen the 30GB version is in Currys using their £20 off £200 promotion code (XMAS20). Also, if you have an Egg card there is a link on their site which gives you 5% cashback at Currys, plus they have double cashback until 16th December, so that would make it around £189, not a bad saving.

If you don't have an Egg card then you will have to use the Quidco link to get 2% off which brings it to around £195.
